A piece of equipment the size of a small house, is to be moved from Immingham Docks to a National Grid substation near Derby.

A new transformer is being delivered to be kept as a spare part and once installed, it will keep lights on in Derbyshire and beyond.

The load, weighing in at 132 tonnes, will be under police escort on the roads as it leaves Immingham.

The massive transporter, which measures 34.5 metres long - will be on the move on Friday, September 7, from 9am to avoid rush hour traffic and is expected to arrive at its destination between 1pm and 3pm.

Roxane Fisher, National Grid project engineer said: "Our network operates smoothly, safely and efficiently over 99.9999 per cent of the time – a statistic we’re very proud of.

The large load will be delivered from Immingham Docks

"Millions of people rely on us to supply their electricity without interruption, day in, day out and so it’s important that we keep our substations and the equipment in them working efficiently."
